True, I don't have a Nobel in economics. But I don't understand why Neil King's and Jonathan Weisman's phrase, "yields on different forms of credit relative to the risk," is not an OK, offhand reference to credit spreads in a newspaper story where credit spreads aren't the central topic.

Paul Krugman gets his boxers all in a bunch about it.

This paragraph is gibberish. What are “yields on different forms of credit relative to the risk”? I don’t know. I suspect that Jared Bernstein was talking about risk spreads — corporate debt versus Treasuries. You might excuse Weisman for getting this garbled — except that Weisman has specialized in reporting on economic issues.

Maybe ""how credit yields varied according to risk" would have been more precise. But geez.
